When previously asked by 'Digital Spy' whether he would consider bringing the cast of 'Downton' to the big screen, Fellowes said the project would be "great fun," but added it may not happen until the series has finished its run on television.

'Downton' first aired on ITV in the UK in 2010 and premiered on PBS in the US on Jan. 9, 2011. The fifth season of 'Downton Abbey,' which is set to air in January 2015, will be its last.
